A homozygous nonsense mutation in the alpha 3 chain gene of laminin 5 (LAMA3) in Herlitz junctional epidermolysis bullosa: prenatal exclusion in a fetus at risk.


Mutations in the three genes (LAMA3, LAMB3, and LAMC2) that encode the three chains (alpha 3, beta 3, and gamma 2, respectively) of laminin 5, a protein involved in epidermal-dermal adhesion, have been established as the genetic basis for the inherited blistering skin disorder, Herlitz junctional epidermolysis bullosa (H-JEB). In this study, we performed… (More)
